e0“Alfalfa ( Medicago sativa L., cv. ‘Vernal’) plants were grown to bud in three temperature regimes”
e1“When plants were retained in the same regime to first flower, days to bud and first flower, dry weight of plant parts, total nonstructural carbohydrate (TNC), and in vitro digestible dry matter (IVDDM) percentages in plant parts increased with a decrease in temperature”

Other claims from this paper (19)
- Intervention effect Dry weight of plant parts increased with a decrease in temperature when plants were kept in the same regime.
- Intervention effect Total nonstructural carbohydrate percentage increased with a decrease in temperature when plants were kept in the same regime.
- Intervention effect In vitro digestible dry matter percentage in plant parts increased with a decrease in temperature when plants were kept in the same regime.
- Intervention effect Concentrations of P, Zn and Mn in the herbage decreased with a decrease in temperature.
- Intervention effect Concentrations of N, K and Fe in the herbage were highest in the H and W regimes and lowest in the C regime.
- Intervention effect Concentrations of Ca, Mg and Ba in the herbage were highest in plants kept in the H regime and lowest but similar in the W and C regimes.
- Intervention effect Concentrations of Sr and B in the herbage were highest in plants kept in the H regime and lowest but similar in the W and C regimes.
- Intervention effect A cooler temperature change between bud and first flower delayed flowering.
- Intervention effect A cooler temperature change between bud and first flower increased dry weights of plant parts.
- Intervention effect A cooler temperature change between bud and first flower increased the percentages of TNC and IVDDM in plant parts.
- Intervention effect A cooler temperature change between bud and first flower decreased mineral concentrations in the herbage.
- Intervention effect A warmer temperature change between bud and first flower had the opposite effect to a cooler change.
- Association Concentrations of TNC, IVDDM and minerals in the herbage at first flower were influenced most by temperature between bud and first flower.
- Association Root TNC percentage at first flower was influenced by temperature both before bud and from bud to first flower.
- Association TNC and IVDDM percentages in the herbage at first flower were highly correlated (r=0.93).
- Association The largest changes in TNC percentage in response to temperature change occurred in leaflets.
- Intervention effect Changing temperature from H to C at bud increased TNC percentage in leaflets by 121% compared with plants held in the H regime.
- Intervention effect Changing from C to H at bud decreased TNC percentage in leaflets by 62% compared with plants held in the C regime.
- Recommendation Alfalfa herbage harvested after a cool period of weather should have greater energy feeding value and silage fermentation capacity than herbage harvested after a warm period.
